This concept applies equally in one, two, and 3-dimensional Areas. The complete crystal lattice may be built by regularly reproducing the sample in the device cell in all directions.
12He tried using once more in quite a few other towns and succeeded with Crystal Caramels.他又在其他几个城市再次尝试,并成功制出了水晶焦糖。
10This will be the silicon chip—somewhat chip of silicon crystal.这是硅芯片——一个硅晶体的小芯片。
Fig. three: A library of lattice symmetries might be accessed by modifying the particle core and DNA shell.
这种水晶观赏石特指水晶晶簇,它是众多单晶体集中生长在一起的晶体组合。晶簇以其晶莹剔透、独特造型而享誉水晶赏石界。
Encyclopaedia Britannica's editors oversee subject matter regions wherein they may have substantial know-how, whether from several years of knowledge attained by working on that information or through examine for an advanced diploma. They publish new written content and confirm and edit content material received from contributors.
⑩、雷射内雕:以计算机辅助激光设备在水晶对象中进行三维图案的成型,艺术效果好,可以任意表达各类图案,图形,达到逼真效果
如果水晶内部杂质中有传说中人物的造型,如佛、星座、生肖等价值可能要高于同等颜色和净度的水晶。
Crystals are frequently viewed as one thing of immense here beauty, plus they are commonly used with diamonds or other stones to create parts of jewellery. The majority of crystals now are man-made in laboratories.
⑤化学稳定�?非常好,在常温下仅溶解于氢氟酸,不溶解于其它各类酸、碱。在高温高压条件下可溶解于碳酸钠溶液中。
用手去触摸水晶,天然水晶通常温度要比人造水晶的要凉的多;用眼观察,天然水晶通常有棉絮状的包裹体,这个是人造水晶所没有的。
正常的水晶在生长时,多可以发现和柱形尖端棱线平行的生长纹(growth lines)。由于在地底、岩洞中的生长空间多狭窄,尤其在遇到地震时,或地壳变动时,甚至容易遭到其他矿石的挤压,常常会压迫产生不同的「晶面」。还有,当水晶还是在液态状的时候,常常也会包覆着其他的矿石、泥灰一起结晶成长,如金红石(稍后变成发晶)、火山泥灰(稍后变成幻影水晶)等等。所有的这些,都是「自然的一部分」,请不要视为「瑕疵」。
This Assessment chronicles around twenty years of exploration into creating a genetic code for crystal engineering. Instead of directing Organic procedures, this code makes use of synthetic forms of DNA to programme the assembly of nanoparticles and microparticles into 1D, 2nd and 3D crystalline architectures, in which just about each and every facet of the resultant constructions may be systematically managed. In this conceptual framework, the structural and purposeful advances are explained in order to define the present level of sophistication and also to predict potential directions with the System.
水晶观赏石在形态、质地、内部特征等方面往往十分奇异。大自然有无限风光,都可以在包裹体水晶种找到缩影。
